Seismic Vulnerability of the Alaskan Way Viaduct: Geotechnical Engineering Aspects
This report describes the geotechnical engineering aspects of a seismic vulnerability analysis of the Alaskan Way Viaduct in Seattle, Washington. Subsurface data from previous investigations for construction of the Alaskan Way Viaduct and other structures in the General area were collected and interpreted. The existing subsurface data was supplemented by additional borings, cone penetration soundings, shear wave velocity tests, and laboratory tests. The existing and supplemental subsurface data was then combined to form a model of the subsurface conditions along the length of the Viaduct. A probablistic seismic hazard analysis was performed to develop design-level ground motions for use in the seismic vulnerability analysis. These ground motions were used as input for site-specific ground response analyses that predicted the nature of ground shaking along the length of the Viaduct. The ground response analyses predicted cycle loading levels that were used in subsequent liquifaction analyses. Foundation stiffness and damping characteristics of the existing foundations were analyzed for use in analyses of the dynamic response of the Alaskan Way Viaduct superstructure.
